Transmission & Distribution

Knowledge and experience are our best assets. Our portfolio covers a wide range of applications: from connectivity solutions ensuring the best tradeoff between safety and flexibility, to outstanding electronic components and analytics to meet the most demanding requirements.

Transmission & Distribution

Contributing to smart grids with high class components

At Weidmüller, we know power utilities are facing many challenges today. Energy transition is a common goal around the globe, and electrical grids play a key role in the decarbonisation targets most of the governments have. Renewable integration, distributed generation, self-consumption, electrical vehicles, etc. will only be possible if electrical grids become smart grids. Smart grids are only possible with digitalisation, communications, cyber-security and analytics. Weidmüller's portfolio offers high class products (from “smart” connectors to Industrial Analytics) to allow power utilities to move towards smart grids keeping their extremely high requirements of reliability and availability.

As a reliable partner for transmission & distribution, our customers can be sure of:

Safety for maintenance personnel

Safety for maintenance personnel

The connections between protection & metering equipment with current transformers may provoke incidents that pose risks to the safety of equipment and personnel. Our aim is to ensure safety on the component side (make-before-break concept), avoiding human mistakes in these critical connections.

Reliable electronic products for harsh environments

Reliable electronic products for harsh environments

We offer a wide range of products meeting the most demanding requirements of Power Utilities: IEC 61850 Ethernet Switches, Class A Quality Analyzers as per IEC 61000-4-30, or Power-Supply family (including UPS) that is being used by international vendors in their solutions for automation of secondary substations, etc.

Industrial analytics for higher added-value services

Industrial analytics for higher added-value services

Smart Metering and Smart Grids allow Power Utilities to have a huge amount of information about their grids. The use of analytics may bring them many improvements in terms of reliability of the grid, quality of the energy, cost savings, safety, etc.

The modernisation and digitalisation of the electrical grids is a key step to achieve the decarbonisation targets of our society. Energy transition is coming and T&D grids are facing major challenges that require smart solutions. At Weidmüller, we are ready to contribute to these solutions with a wide range of different products. Let’s connect!

Facing market challenges with innovation and passion

Smart metering

Smart metering

Smart metering

Traditional revenue meters are being progressively replaced by smart meters at power utilities and at Weidmüller we have developed many different customised DIN-rail assemblies to easily replace and check the meter ensuring the safety of the personnel and equipment. We also have a comprehensive range of surge protection devices (Type I and II) that are being widely used to protect these newly installed electronic meters.

Distribution automation

Distribution automation

Distribution automation

Distribution automation is one of the crucial steps of power utilities towards smart grids. Monitoring and automation of secondary substations require reliable and compact products and the Weidmüller portfolio includes several of the key elements required at the “smart” secondary substations. We can provide the power supply back-up system, the LAN/WAN communications devices, surge protection as well as the necessary components for the internal connectivity.

Substation panels and MV switchgears

Substation panels and MV switchgears

The protection and control system of a substation requires thousands of critical connections with the primary equipment. Weidmüller's full range of modular terminal blocks and markers offers the best alternatives to connect the different type of signals in a reliable and safe way. Our portfolio also includes a comprehensive family of signalling relays, so we can provide the complete set of accessories required in the substation cabinets.

Energy management

Energy Analyser EA 750: reliable, repeatable, and comparable results

Class A devices as per EN61000-4-30 standard guarantee a reliable, repeatable and comparable measurement of the power quality parameters listed in the EN50160 standard. EA 750 is the best option for power utilities to monitor the quality of the grid in order to meet the regulatory requirements, get valuable information for internal purposes, monitor the quality of the energy generated by third parties and respond to customer complaints.

  • Meet the regulatory requirements
  • Gain valuable information for internal purposes
  • Be in a position to respond to customer complaints
  • Monitor energy quality of generation plants connected to the grid
Safe connections in protection and metering

Safe connections in protection and metering

Reliable products with the best tradeoff between safety and flexibility

Our DIN-rail assemblies for metering devices can be customised according to any specific requirements and allow easy replacement or verification of any meter ensuring the required safety for the operation staff. Moreover, we have specific products to avoid any risk in the critical connections of electronic equipment with current transformers (CT).

These products automatically short-circuit the CT side before the connection is opened ensuring total safety during the maintenance operation.
